     The parties hereto agree as follows:

     1.   DEMAND REGISTRATIONS.

          (a)    REQUESTS FOR REGISTRATION. The Securityholders contemplate the
organization of a corporation and reorganization or recapitalization of the LLC
pursuant to SECTION 15.7 of the LLC Agreement. The corporate successor to the
LLC shall be referred to herein as the "COMPANY." At any time after the
organization of the Company, the holders of a majority of the Investor
Registrable Securities may request registration under the Securities Act of all
or any portion of their Registrable Securities on Form S-1 or any similar
long-form registration ("LONG-FORM REGISTRATIONS"), or on Form S-2 or S-3
(including pursuant to Rule 415 under the Securities Act) or any similar
short-form registration ("SHORT-FORM REGISTRATIONS"), if available. In addition,
subject to SECTION 1(c), no earlier than 180 days after the Company has
completed its initial public offering, the holders of a majority of the
TCW/Crescent Registrable Securities may request registration under the
Securities Act of all or part of their Registrable Securities in a Short-Form
Registration, if available. All registrations requested pursuant to this SECTION
1(a) are referred to herein as "DEMAND REGISTRATIONS." Each request for a Demand
Registration shall specify the approximate number of Registrable Securities
requested to be registered and the anticipated per share or per unit price range
for such offering. Within ten days after receipt of any such request, the
Company shall give written notice of such requested registration to all other
holders of Registrable Securities and shall include in such registration all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within 15 days after the receipt of the Company's
notice.

          (b)    INVESTOR LONG-FORM REGISTRATIONS. The holders of Investor
Registrable Securities shall be entitled to request an unlimited number of
Long-Form Registrations in which the Company shall pay all Registration Expenses
(as defined in SECTION 5). All Long-Form Registrations shall be underwritten
registrations.

          (c)    INVESTOR SHORT-FORM REGISTRATIONS. In addition to the Long-Form
Registrations provided pursuant to SECTION 1(b), the holders of Investor
Registrable Securities shall be entitled to request an unlimited number of
Short-Form Registrations in which the Company shall pay all Registration
Expenses and the holders of a majority of the TCW/Crescent Registrable
Securities shall be entitled to request one (1) Short-Form Registration, if
available, in which the Company shall pay all Registration Expenses. Demand
Registrations shall be Short-Form Registrations whenever the Company is
permitted to use any applicable short form. After the Company has become subject
to the reporting requirements of the Securities Exchange Act, the Company shall
use its commercially reasonable efforts to make Short-Form Registrations on Form
S-3 available for the sale of Registrable Securities. If the Company, pursuant
to the request of the holder(s) of a majority of Investor Registrable
Securities, is qualified to and has filed with the Securities Exchange
Commission a registration statement under the Securities Act on Form S-3
pursuant to Rule 415 under the Securities Act (the "REQUIRED REGISTRATION"),
then the Company shall use its best efforts to cause the Required Registration
to be declared effective under the Securities Act as soon as practicable after
filing, and, once effective, the Company shall cause such Required Registration
to remain effective for a period ending on the earlier of (i) the date on which
all Investor Registrable Securities have been sold pursuant to the Required
Registration, or (ii) the date as of which the holder(s) of Investor Registrable
Securities

                                        2
<Page>

(assuming such holder(s) are affiliates of the Company) are able to sell all of
the Investor Registrable Securities then held by them within a ninety-day period
in compliance with Rule 144 under the Securities Act. In the case of a
Short-Form Registration requested by the holders of a majority of the
TCW/Crescent Registrable Securities pursuant to this SECTION 1(c), a
registration shall count as the permitted Short-Form Registration only if the
parties requesting such registration are able to register and sell at least 75%
of their Registrable Securities requested to be included in such registration OR
if an aggregate amount of TCW/Crescent Registrable Securities equal to at least
75% of the TCW/Crescent Registrable Securities outstanding as of the date hereof
has been registered and sold (whether under such Short-Form Registration or one
or more prior registered offerings).

          (d)    PRIORITY ON DEMAND REGISTRATIONS. The Company shall not include
in any Demand Registration any securities that are not Registrable Securities
without the prior written consent of the holders of a majority of the Investor
Registrable Securities included in such registration. If a Demand Registration
is an underwritten offering and the managing underwriters advise the Company in
writing that, in their opinion, the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering
exceeds the number of Registrable Securities and other securities, if any, that
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Investor Registrable Securities
to be included in such registration, then the Company shall include in such
registration, prior to the inclusion of any securities that are not Registrable
Securities, the number of Registrable Securities requested to be included that,
in the opinion of such underwriters, can be sold in an orderly manner within the
price range of such offering, pro rata among the respective holders thereof on
the basis of the amount of Registrable Securities owned by each such holder.

          (e)    RESTRICTIONS ON LONG-FORM REGISTRATIONS. The Company shall not
be obligated to effect any Long-Form Registration within 90 days after the
effective date of a previous Long-Form Registration or a previous registration
in which the holders of Registrable Securities were given piggyback rights
pursuant to SECTION 2 and in which there was no reduction in the number of
Registrable Securities requested to be included. The Company may postpone for up
to 180 days the filing or the effectiveness of a registration statement for a
Demand Registration if the Company and the holders of a majority of the Investor
Registrable Securities agree that such Demand Registration would reasonably be
expected to have a material adverse effect on any proposal or plan by the
Company or any of its Subsidiaries to acquire financing, engage in any
acquisition of assets (other than in the ordinary course of business), or engage
in any merger, consolidation, tender offer, reorganization, or similar
transaction; provided that, in such event, the holders of Investor Registrable
Securities initially requesting such Demand Registration shall be entitled to
withdraw such request and the Company shall pay all Registration Expenses in
connection with such registration. The Company may delay a Demand Registration
hereunder only once in any twelve-month period.

          (f)    SELECTION OF UNDERWRITERS. The holders of a majority of the
Investor Registrable Securities included in any Demand Registration shall have
the right to select the investment banker(s) and manager(s) to administer the
offering.

                                        3
<Page>

          (g)    OTHER REGISTRATION RIGHTS. Except as provided in this
Agreement, the Company shall not grant to any Persons the right to request the
Company to register any equity securities of the Company, or any securities,
options, or rights convertible or exchangeable into or exercisable for such
securities, without the prior written consent of the holders of a majority of
the Investor Registrable Securities.

          (h)    OBLIGATIONS OF HOLDERS OF REGISTRABLE SECURITIES. Subject to
the Company's obligations under SECTION 4(e) hereof, each holder of Registrable
Securities shall cease using any prospectus after receipt of written notice from
the Company of the happening of any event as a result of which such prospectus
contains an untrue statement of a material fact or omits any fact necessary to
make the statements therein not misleading in light of the circumstances under
which they were made.

     2.   PIGGYBACK REGISTRATIONS.

          (a)    RIGHT TO PIGGYBACK. Whenever the Company proposes to register
any of its securities (including any proposed registration of the Company's
securities by any third party) under the Securities Act (other than (i) pursuant
to a Demand Registration, to which SECTION 1 is applicable, (ii) in connection
with an initial public offering of the Company's equity securities (other than
an initial public offering in which any holder of Registrable Securities is
entitled to participate), or (iii) in connection with registrations on Form S-4,
S-8 or any successor or similar forms) and the registration form to be used may
be used for the registration of Registrable Securities (a "PIGGYBACK
REGISTRATION"), the Company shall give prompt written notice (and in any event
within three business days after its receipt of notice of any exercise of demand
registration rights other than under this Agreement) to all holders of
Registrable Securities of its intention to effect such a registration and shall
include in such registration all Registrable Securities with respect to which
the Company has received written requests for inclusion therein within 20 days
after the receipt of the Company's notice.

          (b)    PIGGYBACK EXPENSES. The Registration Expenses of the holders of
Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

          (c)    PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration
is an underwritten primary registration on behalf of the Company, and the
managing underwriters advise the Company in writing that, in their opinion, the
number of securities requested to be included in such registration exceeds the
number which can be sold in an orderly manner in such offering within a price
range acceptable to the Company, then the Company shall include in such
registration (i) first, the securities the Company proposes to sell, (ii)
second, the Registrable Securities requested to be included in such
registration, pro rata among the holders of such Registrable Securities on the
basis of the number of shares or units owned by each such holder, and (iii)
third, the other securities requested to be included in such registration.

          (d)    PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities other than holders of Registrable Securities (it being
understood that secondary registrations on behalf of holders of Registrable
Securities are addressed in SECTION 1 above rather than this SECTION 2(d)), and
the managing underwriters advise the Company in writing that, in their opinion,
the number

                                        4
<Page>

of securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Investor Registrable Securities
to be included in such registration, then the Company shall include in such
registration (i) first, the securities requested to be included therein by the
holders requesting such registration, (ii) second, the Registrable Securities
requested to be included in such registration, pro rata among the holders of
such Registrable Securities on the basis of the number of shares or units owned
by each such holder, and (iii) third, the other securities requested to be
included in such registration.

          (e)    SELECTION OF UNDERWRITERS. If any Piggyback Registration is an
underwritten offering, then the selection of investment banker(s) and manager(s)
for the offering must be approved by the holders of a majority of the Investor
Registrable Securities included in such Piggyback Registration. Such approval
shall not be unreasonably withheld.

          (f)    OTHER REGISTRATIONS. If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 1 or pursuant to this Section 2, and if such previous registration has
not been withdrawn or abandoned, then, unless such previous registration is a
Required Registration, the Company shall not file or cause to be effected any
other registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Securities
Act (except on Form S-8 or any successor form), whether on its own behalf or at
the request of any holder or holders of such securities, until a period of at
least 180 days has elapsed from the effective date of such previous
registration.

     3.   HOLDBACK AGREEMENTS.

          (a)    To the extent not inconsistent with applicable law, each holder
of Registrable Securities shall not effect any public sale or distribution
(including sales pursuant to Rule 144) of equity securities of the Company, or
any securities, options, or rights convertible into or exchangeable or
exercisable for such securities, (i) in the case of an initial public offering,
during the seven days prior to and the 180-day period beginning on the effective
date of the registration statement relating to such initial public offering (or
such shorter period as agreed to by the underwriters managing such registered
public offering) or (ii) in all cases other than an initial public offering,
during the seven days prior to and the 90-day period beginning on the effective
date of the registration statement relating to any underwritten Demand
Registration or any underwritten Piggyback Registration (or such shorter period
as agreed to by the underwriters managing such registered public offering), in
each case in which Registrable Securities are included (except as part of such
underwritten registration or pursuant to registrations on Form S-4 or Form S-8
or any successor form), unless the underwriters managing the registered public
offering otherwise agree.

          (b)    The Company (i) shall not effect any public sale or
distribution of its equity securities, or any securities, options, or rights
convertible into or exchangeable or exercisable for such securities, during the
seven days prior to and during the 180-day period beginning on the effective
date of any underwritten Demand Registration or any underwritten Piggyback
Registration (except as part of such underwritten registration or pursuant to
registrations on Form S-8 or any successor form), unless the underwriters
managing the

                                        5
<Page>

registered public offering otherwise agree, and (ii) to the extent not
inconsistent with applicable law, shall cause each holder of its equity
securities, or any securities convertible into or exchangeable or exercisable
for equity securities, purchased from the Company at any time after the date of
this Agreement (other than in a registered public offering) to agree not to
effect any public sale or distribution (including sales pursuant to Rule 144) of
any such securities during such period (except as part of such underwritten
registration, if otherwise permitted), unless the underwriters managing the
registered public offering otherwise agree.

     4.   REGISTRATION PROCEDURES. Whenever the holders of Registrable
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company shall use its commercially reasonable efforts to
effect the registration and the sale of such Registrable Securities in
accordance with the intended method of disposition thereof, and pursuant thereto
the Company shall as expeditiously as possible:

          (a)    prepare and, within 60 days after the end of the period within
which requests for registration may be given to the Company, file with the
Securities and Exchange Commission a registration statement with respect to such
Registrable Securities and use its commercially reasonable efforts to cause such
registration statement to become effective (provided that, before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company shall furnish to the counsel selected by the holders of a majority
of the Investor Registrable Securities covered by such registration statement
copies of all such documents proposed to be filed, which documents shall be
subject to the review and comment of such counsel);

          (b)    notify in writing each holder of Registrable Securities of the
effectiveness of each registration statement filed hereunder and prepare and
file with the Securities and Exchange Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective for a period
of not less than 180 days (or, if such registration statement relates to an
underwritten offering, such longer period as in the opinion of counsel for the
underwriters a prospectus is required by law to be delivered in connection with
sales of Registrable Securities by an underwriter or dealer) and comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

          (c)    furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus), and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)    use its commercially reasonable efforts to register or qualify
such Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
of Registrable Securities to consummate the disposition in such jurisdictions of
the Registrable Securities owned by such seller of Registrable

                                        6
<Page>

Securities (provided that the Company shall not be required to (i) qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this SECTION 4(d), (ii) subject itself to taxation
in any such jurisdiction, or (iii) consent to general service of process in any
such jurisdiction);

          (e)    promptly notify in writing each seller of such Registrable
Securities, at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event as a result of
which the prospectus included in such registration statement contains an untrue
statement of a material fact or omits any fact necessary to make the statements
therein not misleading in light of the circumstances under which they were made,
and, at the request of the holders of a majority of the Registrable Securities
covered by such registration statement, the Company shall promptly prepare and
furnish to each such seller a reasonable number of copies of a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus shall not contain an untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading in light of the circumstances under which they
were made;

          (f)    cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, use its
commercially reasonable efforts to secure designation of all such Registrable
Securities covered by such registration statement as a NASDAQ "national market
system security" within the meaning of Rule 11Aa2-1 of the Securities and
Exchange Commission or, failing that, to secure NASDAQ authorization for such
Registrable Securities;

          (g)    provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)    enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of
Registrable Securities (including effecting a unit split or a combination of
units);

          (i)    make available for inspection by any underwriter participating
in any disposition pursuant to such registration statement, and any attorney,
accountant, or other agent retained by any such underwriter, all financial and
other records, pertinent corporate documents and properties of the Company, and
cause the Company's officers, directors, employees, and independent accountants
to supply all information reasonably requested by any such underwriter,
attorney, accountant, or agent in connection with such registration statement
and assist and, at the request of any participating underwriter, use
commercially reasonable efforts to cause such officers or directors to
participate in presentations to prospective purchasers;

          (j)    otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve months beginning with
the first day of the Company's first full calendar quarter after the

                                        7
<Page>

effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder;

          (k)    in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any equity securities included in such registration statement for sale in any
jurisdiction, the Company shall use its commercially reasonable efforts promptly
to obtain the withdrawal of such order;

          (l)    use its commercially reasonable efforts to cause such
Registrable Securities covered by such registration statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to enable the sellers thereof to consummate the disposition of such
Registrable Securities;

          (m)    obtain one or more cold comfort letters, dated the effective
date of such registration statement (and, if such registration includes an
underwritten public offering, dated the date of the closing under the
underwriting agreement), from the Company's independent public accountants in
customary form and covering such matters of the type customarily covered by cold
comfort letters as the holders of a majority of the Investor Registrable
Securities being sold in such registered offering reasonably request (provided
that such Investor Registrable Securities constitute at least 10% of the
securities covered by such registration statement); and

          (n)    provide a legal opinion of the Company's outside counsel, dated
the effective date of such registration statement (or, if such registration
includes an underwritten public offering, dated the date of the closing under
the underwriting agreement), with respect to the registration statement, each
amendment and supplement thereto, the prospectus included therein (including the
preliminary prospectus) and such other documents relating thereto in customary
form and covering such matters of the type customarily covered by legal opinions
of such nature.

     5.   REGISTRATION EXPENSES.

          (a)    Subject to SECTION 5(b) below, all expenses incident to the
Company's performance of or compliance with this Agreement, including all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws, printing expenses, travel expenses, filing expenses, messenger

Company (all such expenses being herein called "REGISTRATION EXPENSES"), shall
be borne as provided in this Agreement, except that the Company shall, in any
event, pay its internal expenses (including all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, the expense of any liability insurance,
and the expenses and fees for listing the securities to be registered on each

                                        8
<Page>

securities exchange on which similar securities issued by the Company are then
listed or on the NASD automated quotation system (or any successor or similar
system).

          (b)    In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse (i) the holders of Registrable
Securities included in such registration for the reasonable fees and
disbursements of one counsel chosen by the holders of a majority of the Investor
Registrable Securities included in such registration and (ii) the TCW/Crescent
Lenders included in such registration up to $15,000.00 for the reasonable fees

          (c)    To the extent Registration Expenses are not required to be paid
by the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
shall be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

     6.   INDEMNIFICATION.

          (a)    The Company agrees to indemnify and hold harmless, to the
fullest extent permitted by law, each holder of Registrable Securities, its
officers, directors, agents, and employees, and each Person who controls such
holder (within the meaning of the Securities Act) against all losses, claims,
damages, liabilities, and expenses (or actions or proceedings, whether commenced
or threatened, in respect thereof), whether joint and several or several,
together with reasonable costs and expenses (including reasonable attorney's
fees) to which any such indemnified party may become subject under the
Securities Act or otherwise (collectively, "LOSSES") caused by, resulting from,
arising out of, based upon, or relating to (i) any untrue or alleged untrue
statement of material fact contained in (A) any registration statement,
prospectus or preliminary prospectus, or any amendment thereof or supplement
thereto or (B) any application or other document or communication (in this
SECTION 6, collectively called an "APPLICATION") executed by or on behalf of the
Company or based upon written information furnished by or on behalf of the
Company filed in any jurisdiction in order to qualify any securities covered by
such registration under the "BLUE SKY" or securities laws thereof or (ii) any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will
reimburse such holder and each such director, officer, and controlling Person
for any legal or any other expenses incurred by them in connection with
investigating or defending any such Losses; provided that the Company shall not
be liable in any such case to the extent that any such Losses result from, arise
out of, are based upon, or relate to an untrue statement or alleged untrue
statement, or omission or alleged omission, made in such registration statement,
any such prospectus, or preliminary prospectus or any amendment or supplement
thereto, or in any application, in reliance upon, and in conformity with,
written information prepared and furnished in writing to the Company by such
holder expressly for use therein or by such holder's failure to deliver a copy
of the registration statement or prospectus or any amendments or supplements
thereto after the Company has furnished such holder with a sufficient number of
copies of the same. In connection with an underwritten offering, the Company
shall indemnify such underwriters, their officers and directors, and each Person
who controls such underwriters (within the meaning of the Securities Act) to the
same

                                        9

extent as provided above with respect to the indemnification of the holders of
Registrable Securities.

          (b)    In connection with any registration statement in which a holder
of Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the fullest extent permitted by law, shall indemnify and hold
harmless the other holders of Registrable Securities and the Company, and their
respective officers, directors, agents, and employees, and each other Person who
controls the Company (within the meaning of the Securities Act) against any
Losses caused by, resulting from, arising out of, based upon, or relating to (i)
any untrue or alleged untrue statement of material fact contained in the
registration statement, prospectus or preliminary prospectus, or any amendment
thereof or supplement thereto or in any application, or (ii) any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is made in such registration statement, any such
prospectus or preliminary prospectus or any amendment or supplement thereto, or
in any application in reliance upon and in conformity with written information
prepared and furnished to the Company by such holder expressly for use therein,
and such holder will reimburse the Company and each such other indemnified party
for any legal or any other expenses incurred by them in connection with
investigating or defending any such Losses; provided that the obligation to
indemnify will be individual, not joint and several, for each holder and shall
be limited to the net amount of proceeds received by such holder from the sale
of Registrable Securities pursuant to such registration statement.

          (c)    Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's right to indemnification hereunder to the extent
such failure has not prejudiced the indemnifying party) and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed and
diligently undertaken, then the indemnifying party will not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent will not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

          (d)    The indemnification provided for under this Agreement shall be
in addition to any other rights to indemnification or contribution which any
indemnified party may have pursuant to law or contract, and will remain in full
force and effect regardless of any investigation made or omitted by or on behalf
of the indemnified party or any officer, director, or controlling Person of such
indemnified party and shall survive the transfer of securities.

                                       10

          (e)    If the indemnification provided for in this SECTION 6 is
unavailable to or is insufficient to hold harmless an indemnified party under
the provisions above in respect to any Losses referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such Losses (i) in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and the
sellers of Registrable Securities and any other sellers participating in the
registration statement on the other hand or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, then in such proportion as
is appropriate to reflect not only the relative fault referred to in clause (i)
above but also the relative benefit of the Company on the one hand and of the
sellers of Registrable Securities and any other sellers participating in the
registration statement on the other in connection with the statement or
omissions which resulted in such Losses, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the sellers of Registrable Securities and any other sellers participating in
the registration statement on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) to the Company bear to the total net proceeds from the offering
(before deducting expenses) to the sellers of Registrable Securities and any
other sellers participating in the registration statement. The relative fault of
the Company on the one hand and of the sellers of Registrable Securities and any
other sellers participating in the registration statement on the other shall be
determined by reference to, among other things, whether the untrue statement or
alleged omission to state a material fact relates to information supplied by the
Company or by the sellers of Registrable Securities or other sellers
participating in the registration statement and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

          (f)    The Company and the sellers of Registrable Securities agree
that it would not be just and equitable if contribution pursuant to this SECTION
6 were determined by pro rata allocation (even if the sellers of Registrable
Securities were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to in SECTION 6(e) above. The amount paid or payable by an indemnified
party as a result of the Losses referred to in SECTION 6(e) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this SECTION 6, no seller of Registrable Securities shall be
required to contribute pursuant to this SECTION 6 any amount in excess of the
sum of (i) any amounts paid pursuant to SECTION 6(b) above and (ii) the net
proceeds received by such seller from the sale of Registrable Securities covered
by the registration statement filed pursuant hereto. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

     7.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

          (a)    No Person may participate in any underwritten registration
hereunder unless such Person (i) agrees to sell such Person's securities on the
basis provided in any underwriting arrangements approved by the Person or
Persons entitled hereunder to approve such arrangements (including pursuant to
the terms of any over-allotment or "GREEN SHOE" option requested by the managing
underwriter(s), provided that no holder of Registrable Securities will

                                       11
<Page>

be required to sell more than the number of Registrable Securities that such
holder has requested the Company to include in any registration) and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements, and other documents reasonably required under the terms
of such underwriting arrangements; provided that no holder of Registrable
Securities included in any underwritten registration shall be required to make
any representations or warranties to the Company or the underwriters (other than
representations and warranties regarding such holder and such holder's intended
method of distribution) or to undertake any indemnification obligations to the
Company or the underwriters with respect thereto, except as otherwise provided
in Section 6 hereof.

          (b)    Each Person that is participating in any registration hereunder
agrees that, upon receipt of any notice from the Company of the happening of any
event of the kind described in SECTION 4(e) above, such Person will immediately
discontinue the disposition of its Registrable Securities pursuant to the
registration statement until such Person's receipt of the copies of a
supplemented or amended prospectus as contemplated by SECTION 4(e). In the event
the Company shall give any such notice, the applicable time period mentioned in
SECTION 4(b) during which a Registration Statement is to remain effective shall
be extended by the number of days during the period from and including the date
of the giving of such notice pursuant to this SECTION 7(b) to and including the
date when each seller of a Registrable Security covered by such registration
statement shall have received the copies of the supplemented or amended
prospectus contemplated by SECTION 4(e).

     8.   ADDITIONAL SECURITYHOLDERS. In connection with the issuance of any
additional equity securities of the Company, the Company, with the consent of
GTCR Fund VIII, may permit such Person to become a party to this Agreement and
succeed to all of the rights and obligations of a holder of any particular
category of Registrable Securities under this Agreement by obtaining an executed
counterpart signature page to this Agreement, and, upon such execution, such
Person shall for all purposes be a holder of such category of Registrable
Securities and party to this Agreement.

     9.   SUBSIDIARY PUBLIC OFFERING. If, after an initial public offering of
the equity securities of a Subsidiary of the LLC, the LLC distributes securities
of such Subsidiary to members of the LLC, then the rights and obligations of the
Company pursuant to this Agreement shall apply, mutatis mutandis, to such
Subsidiary, and the LLC or the Company, as applicable, shall cause such
Subsidiary to comply with such Subsidiary's obligations under this Agreement.

     10.  CURRENT PUBLIC INFORMATION. At all times after the Company has filed a
registration statement with the Securities and Exchange Commission pursuant to
the requirements of either the Securities Act or the Securities Exchange Act,
the Company shall file all reports required to be filed by it under the
Securities Act and the Securities Exchange Act and the rules and regulations
adopted by the Securities and Exchange Commission thereunder and shall take such
further action as any holder or holders of Registrable Securities may reasonably
request, all to the extent required to enable such holders to sell Registrable
Securities pursuant to (i) Rule 144 adopted by the Securities and Exchange
Commission under the Securities Act (as such rule may be amended from time to
time) or any similar rule or regulation hereafter adopted by the Securities and
Exchange Commission or (ii) a registration statement on Form S-2 or S-3 or any
similar registration form hereafter adopted by the Securities and Exchange
Commission.

Securities in this Agreement.

such Registrable Securities in any such registration (including effecting a unit
split or a combination of units).

          (c)    REMEDIES. Any Person having rights under any provision of this
Agreement shall be entitled to enforce such rights specifically, to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any

                                       15
<Page>

bond or other security) for specific performance and for other injunctive relief

          (d)    AMENDMENTS AND WAIVERS. Except as otherwise provided herein, no
modification, amendment, or waiver of any provision of this Agreement shall be

the Common Units (as defined in the LLC Agreement); PROVIDED THAT, no such
amendment or modification that would materially and adversely affect holders of
one class or group of Registrable Securities in a manner different than holders
of any other class or group of Registrable Securities (other than amendments and
modifications required to implement the provisions of SECTION 8) shall be
effective against the holders of such class or group of Registrable Securities
without the prior written consent of holders of at least a majority of
Registrable Securities of such class or group materially and adversely affected
thereby. No failure by any party to insist upon the strict performance of any
covenant, duty, agreement, or condition of this Agreement or to exercise any
right or remedy consequent upon a breach thereof shall constitute a waiver of
any such breach or any other covenant, duty, agreement, or condition.

          (e)    SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Agreement by or on behalf of any of the parties hereto shall bind and inure to
the benefit of the respective successors and assigns of the parties hereto
whether so expressed or not. In addition, whether or not any express assignment

holder of Registrable Securities must execute a counterpart to this Agreement,
thereby agreeing to be bound by the terms hereof.

          (f)    SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          (g)    COUNTERPARTS. This Agreement may be executed simultaneously in
two or more counterparts (including by means of facsimile), any one of which
need not contain the signatures of more than one party, but all such
counterparts taken together shall constitute one and the same Agreement.

          (h)    DESCRIPTIVE HEADINGS. The descriptive headings of this
Agreement are inserted for convenience only and do not constitute a substantive
part of this Agreement.

Whenever required by the context, any pronoun used in this Agreement shall
include the corresponding masculine, feminine, or neuter forms, and the singular
form of nouns, pronouns, and verbs shall include the plural and vice versa. The
use of the word "INCLUDING" in this Agreement shall be, in each case, by way of
example and without limitation. The use of the words "or," "either," and "any"

Delaware General Corporation Law, as applicable, shall govern all issues and
questions concerning the relative rights of the LLC, the Company and its
securityholders. All other issues and questions concerning the construction,
validity, interpretation, and enforcement of this Agreement and the exhibits and
schedules hereto shall be governed by, and construed in accordance with, the
laws of the State of Delaware, without giving effect to any choice of law or
conflict of law rules or provisions (whether of the State of Delaware or any
other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware

          (j)    MUTUAL WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN
CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND
FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT
THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE,
TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ALL RIGHTS TO TRIAL BY
JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN
OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR
OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

headquarters or to such other address or to the attention of such other Person
as the recipient party has specified by prior written notice to the sending
party.

          (l)    ENTIRE AGREEMENT. This Agreement, those documents expressly
referred to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt any
prior understandings,

                                       17
<Page>

agreements or representations by or among the parties, written or oral, which
may have related to the subject matter hereof in any way.

          (m)    NO STRICT CONSTRUCTION. The parties hereto have participated
jointly in the negotiation and drafting of this Agreement. In the event an
ambiguity or question of intent or interpretation arises, this Agreement shall
be construed as if drafted jointly by the parties hereto, and no presumption or
burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any of the provisions of this Agreement.
